As of March 17th, the United States Embassy in Addis Ababa Ethiopia, is cancelling Immigrant and Nonimmigrant visa appointments. We will resume routine visa services as soon as possible but are unable to provide a specific date at this time. The MRV fee is valid and may be used for a visa application in the country where it was purchased within one year of the date of payment. If you have an urgent matter and need to travel immediately, please contact at weeac_contactus+et+info+en@visaops.net or at +251 115 582424 for assistance provided by the Ethiopia-based call center or at +1 703 543 9339 if you are calling from within the United States to request an emergency appointment.
